The evolutionary history of a set of taxa is usually represented by a phylogenetic tree, and
this model has greatly facilitated the discussion and testing of hypotheses. However, it is well …

Recombination is a powerful evolutionary force that merges historically distinct genotypes.
But the extent of recombination within many organisms is unknown, and even determining its …

There is continuing debate about the impact of agricultural practices on farmland wildlife. In
particular, it has been postulated that a general decline in insect abundance linked with …

The multispecies coalescent provides an elegant theoretical framework for estimating species
trees and species demographics from genetic markers. However, practical applications of …

To form epithelial organs cells must polarize and generate de novo an apical domain and
lumen. Epithelial polarization is regulated by polarity complexes that are hypothesized to …

Fluid attenuated inversion recovery pulse sequences with a long echo time (TE) have been
used to image the brain in one volunteer and four patients. The long inversion time used with …
